[0025] The scraper installation device described above will be described below in conjunction with specific embodiments to further understand the utility model concept of the scraper installation device.

[0026] In one embodiment, if Figure 1-2 As shown, a scraper installation device includes a support platform 100 and a width adjustment assembly 200 slidably connected to the support platform 100, the width adjustment assembly 200 includes at least two brackets 210 and a support column 220 supporting each of the brackets 210; at least two guide rails 110 are arranged on the support platform 100, the extension direction of the guide rails 110 is perpendicular to the extension direction of the brackets 210, and the support column 240 supporting the two outermost brackets 210 can slide along the guide rails 110. Preferably, two guide rails 110 are arranged, which are located at the two ends of the support platform 100. In this embodiment, when installing the scraper, first adjust the distance between the two brackets 210 according to the width of the scraper. Specifically, apply force to the two brackets 210, and the support column 240 fixedly connected thereto will slide along the guide rail 110. When the distance between the two brackets 210 meets the width requirement of the scraper, stop sliding the support column, fix the two chains on the upper end surfaces of the two brackets 210 respectively, and install the scraper between the two chains in turn. When the scraper at the current station is installed, move the chain to the next scraper installation station until all the scrapers on the chain are installed. The scraper installation device provided in this embodiment can place the chain on the support platform 100 to complete the installation. The staff does not need to move back and forth, but only needs to move the chain to complete the installation of the scraper on the entire chain while standing or sitting at one station, which saves time and effort. In addition, the distance between the two brackets 210 used to support the chain can be adjusted to meet the installation requirements of scrapers of different widths, and has high applicability. Preferably, a slider 221 that slides with the guide rail 110 is provided at the lower end of the support column 220, and the distance between the two brackets 210 is adjusted by sliding the slider 241 with the guide rail 110. Preferably, arc-shaped recesses 130 are provided on both sides of the support platform, and the staff can stand or sit in the arc-shaped recesses 130 to facilitate the staff's operation.

[0027] In another embodiment, if Figure 1 As shown, the width adjustment assembly further includes a ball screw 230 and a hand wheel 260 disposed at one end of the ball screw 230; the ball screw 230 is mounted on the support platform 100 via a seat bearing 232; the ball screw 230 is rotatably connected to at least one of the two outermost brackets 210. That is, by rotating the hand wheel 260, at least one bracket 210 rotatably connected to the ball screw 230 can slide along the guide rail 11, thereby adapting to the installation of scrapers of different widths.

[0028] In another embodiment, if Figure 1As shown, two nuts 231 with opposite tapping directions are installed on the ball screw 230, and a connecting piece 233 is arranged on each of the nuts 231, and the connecting piece 233 is fixedly connected to the bracket 210. When adjusting the distance between the two brackets 210, the hand wheel 260 is rotated, and the two nuts 231 with opposite tapping directions on the ball screw 230 will drive the two brackets 210 to move in opposite directions, that is, according to the width of the scraper, the nut 231 on the ball screw 230 can drive the two brackets 210 to move closer or farther from each other by rotating the hand wheel 260 forward or reversely. That is, in the utility model, two nuts 231 with opposite tapping directions are arranged on the ball screw 230, and the nuts 231 are fixedly connected to the bracket 210, and the distance between the two brackets 210 can be adjusted by rotating the ball screw 230, which is convenient for the staff to adjust and improves the efficiency of assembly.

[0029] In another embodiment, a plurality of baffles are respectively provided on both sides of the two outermost brackets 210, and the chain 400 is provided on the upper end surface of the bracket. The baffles limit the position of the chain 400 to prevent the chain 400 from being offset when the scraper is installed.

[0030] In another embodiment, a plurality of magnets are respectively disposed on the upper end surfaces of the two outermost brackets 210, and the chain 400 is fixed to the upper end surfaces of the brackets 210 by the magnets to facilitate the installation of the scraper and prevent the chain from being offset during the installation of the scraper.

[0031] In another embodiment, if Figure 1-2As shown, pulleys 250 are respectively arranged at both ends of each of the brackets 210, and a synchronous belt 240 is arranged around the pulleys 250; a driving unit 120 is also arranged on the support platform 100, and the pulleys 250 are driven by the driving unit 120 to drive the synchronous belt 240 to rotate. In this embodiment, a synchronous belt 240 is arranged around the length direction of the bracket 210, and the synchronous belt 240 can rotate around the pulley 250. The driving unit 120 drives the pulley 250 to rotate, and the pulley 250 drives the synchronous belt 240 to rotate. Two chains 400 are arranged on the synchronous belt 240, and the synchronous belt 240 can drive the chain 400 to move forward. When the scraper corresponding to the workstation where the staff is located is installed, the driving unit is started, and the synchronous belt 240 drives the chain to move to the next scraper installation station to complete the installation of the scraper, and this cycle is repeated until the installation of the scraper on the entire chain is completed. That is, for the scraper installation device provided in this embodiment, the worker only needs to be fixed at the corresponding workstation. Preferably, the worker stands or sits at the location of the arc-shaped notch 130 without moving. The installation of all scrapers on the chain can be completed by only moving the synchronous belt to drive the chain. In this embodiment, when adjusting the distance between the two synchronous belts 240 to meet the width of the scraper, because the synchronous belts 240 are fixed to the bracket 210 through the pulley 250, the distance between the two synchronous belts 240 can be adjusted by turning the hand wheel.

Correspondingly, each bracket 210 is provided with a pulley 250 and a synchronous belt 240. The two synchronous belts 240 on both sides are used to place the chain 400, and the pulley 250 at one end of each bracket 210 is coaxially arranged. The pulley 250 at the end of the middle bracket 210 is rotatably connected to the output shaft of the driving unit 120. The driving unit 120 drives the pulley 250 at the end of the middle bracket 210 to rotate, so that the pulleys 250 at the ends of the brackets 210 on both sides coaxially arranged therewith also rotate accordingly.

[0033] In another embodiment, if Figure 1 and Figure 3 As shown, a plurality of positioning posts 242 are respectively provided on the two outermost synchronous belts 240 . The positioning posts 242 pass through the gaps on the chain 400 to fix the chain 400 on the synchronous belt 240 , so that the chain 400 rotates with the synchronous belt 240 .

[0034] In another embodiment, if Figure 1 and Figure 3 As shown, a plurality of limit blocks 243 are respectively provided on the sides of the two outermost synchronous belts 240 , and the limit blocks 243 are used to limit the position of the chain 400 to prevent the chain from deviating during movement, thereby ensuring that the chain 400 moves in a straight line.
